Gone are the existing 70-watt high-pressure sodium and 100-watt metal halide fixtures that are being replaced with 2,300 45-watt light-emitting diode (LED) lights. The LED lights will halve energy use in the Lincoln Tunnel resulting in net energy savings of 1.2 million kilowatt-hours annually.

The work is part of a broader $8.7 million energy conservation initiative by the Port Authority to reduce costs in the Lincoln Tunnel and at the Port Authority Bus Terminal in Midtown Manhattan. Altogether, the initiatives will save the Port Authority $1 million in annual energy cost savings over the next 15 years.

Committed to reduce energy use at all of it's operations, the Port Authority'senergy conservation programuses benchmark energy data in its buildings and facilities to implement energy efficiency projects.
